Helpful link. That's what it says, presumably "Dawn Flight" was made a decade or so before this SB and the aerobatics in the film were pre-CGI? Was there also an AD that forbade aerobatics and required it be placarded as with some other aircraft? I have a 1-35 and will not do aerobatics w/ or w/o an AD. Thanks.
